If you can't find the galleries, then you will have to drill in between the studs and foam the entire wall cavity. This is hard to do with a can of foam. The Solo Foamer with Termidor SC is much more economical when doing wall cavity foaming.
Bora Care is good for preventive Drywood termite control. If you have existing Drywood termites, Termidor is the way to go.
Hope this helps.
